Well, it seems Facebook took her "like" and her friend's list, and used it to target me with an ad in my Facebook timeline on behalf of a paying political client.
The campaign in question is Michelle Nunn's.
I got a screen grab of Nunn's Facebook timeline ad, including the "like" mentions at the top (but redacted my friend's name before posting here). The ad, marked as "sponsored," linked to Nunn's campaign Facebook page.
Gotta remember people, when you see ads like this, a Facebook "like" is not necessarily synonymous with a political endorsement.
